I was testing this new version and speed is almost the same
image in screen 340x480/4 152/14 ms

VESA VBE 2.0 MagicGraph 128XD 40K SVGA BIOS [1984 kB]
probing 640x480/16
VideoModeNumber = 111h
614400 B allocated for FrameBuffer
WinFuncPtr = C000:1BF4h
WinGranularity = 64 kB
NumBanks = 9
LastSize = 24576 B
Measured refresh rate = 60.6 Hz
Measured 45 FPS (FrameBuffer>VRAM)
(transfer speed 26 MB/s)

I notice that I never enabled write combing under msdos.. Ill try with it... mayeb I gain some speed
